Introduction

One of the common errors that Git users, especially on Windows, encounter is the error: unable to create file (Filename too long). This error occurs when Git tries to create or access files with path lengths that exceed the system’s limits, leading to problems in cloning, pulling, or checking out branches. In this in-depth guide, we will explore the root causes of this error, focusing on how the “Git filename too long” issue manifests and how you can fix it with a variety of approaches, from basic settings to advanced solutions.

What Causes the ‘Git Filename Too Long’ Error?

The Git filename too long error occurs when the length of a file path exceeds the limit imposed by the operating system or file system. While Git itself doesn’t restrict file path lengths, operating systems like Windows do.

1. Windows Path Length Limitations

On Windows, the maximum length for a path (file name and directory structure combined) is 260 characters by default. This is called the MAX_PATH limit. When a repository has files or folders with long names, or a deeply nested structure, the total path length might exceed this limit, causing Git to fail when creating or accessing those files.

2. Deeply Nested Directory Structures

If your Git repository contains deeply nested directories, the combined length of folder names and file names can quickly surpass the path length limit, resulting in the error.

3. Automatically Generated Filenames

Certain tools or build processes might generate long file names automatically, which are often difficult to shorten manually.

How to Fix ‘Git Filename Too Long’ Error

There are multiple ways to fix the ‘Git filename too long’ error. Depending on your use case and the system you’re working on, you can opt for simple configuration changes or more advanced methods to resolve this issue.

1. Enable Long Paths in Windows 10 and Later

Windows 10 and later versions support long paths, but the feature is disabled by default. You can enable it through Group Policy or the Registry Editor.

Steps to Enable Long Paths in Windows 10:

Via Group Policy (Windows Pro and Enterprise):

Press Win + R and type gpedit.msc to open the Group Policy Editor.
Navigate to Computer Configuration > Administrative Templates > System > Filesystem.
Double-click on “Enable Win32 long paths”.
Set the policy to Enabled and click OK.

Via Registry (Windows Home and Other Editions):

Press Win + R, type regedit, and press Enter.
Navigate to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
Create a new DWORD (32-bit) entry and name it LongPathsEnabled.
Set its value to 1.
Restart your system to apply the changes.

Enabling long paths ensures that Git can handle file paths longer than 260 characters, fixing the error for most Git operations.

2. Set `core.longpaths` in Git Configuration

Git offers a built-in configuration option to allow it to handle long file paths. This solution is ideal for users who cannot or do not wish to modify their system’s configuration.

Steps to Enable Long Paths in Git:

Open Git Bash or the Command Prompt.
Run the following command:
- git config --system core.longpaths true

This command configures Git to support long file paths on your system. Once enabled, Git can work with file paths exceeding the 260-character limit, eliminating the filename too long error.

3. Shorten File and Directory Names

A straightforward method to solve the Git filename too long issue is to reduce the length of directory and file names in your repository. This may require some restructuring, but it is effective, particularly for projects with very deep directory nesting or unnecessarily long filenames.

Example:

Instead of using a long folder path like:

C:/Users/huupv/Documents/Projects/Work/Repositories/SuperLongProjectName/this/is/an/example/of/a/very/deep/folder/structure/index.js

You could simplify it by moving the project closer to the root of your drive:

C:/Repos/SimpleProject/index.js

Shortening directory names helps you avoid exceeding the 260-character limit, fixing the error without altering system settings.

4. Clone Repository to a Shorter Path

The location where you clone your repository can contribute to the path length. If the directory into which you’re cloning your project has a long path, it adds to the overall file path length.

Steps to Shorten Path for Git Cloning:

Instead of cloning the repository to a deeply nested directory, try cloning it closer to the root directory:

git clone https://github.com/username/repository.git C:/Repos/MyRepo

By reducing the initial directory path length, you decrease the chances of encountering the Git filename too long error.

5. Use Git Submodules to Manage Large Repositories

If your project contains a massive directory structure or very long filenames, you might consider breaking it up into smaller repositories using Git submodules. This solution helps to divide large projects into manageable parts, reducing the chance of hitting path length limitations.

Example Workflow:

Identify large directories in your repository that can be separated into individual repositories.
Create new repositories for these sections.
Use Git submodules to link these repositories back into your main project:

git submodule add https://github.com/username/large-repo-part.git

This method is more advanced but is useful for developers managing large, complex repositories.

6. Using Git Bash with Windows and Long Path Support

When using Git on Windows, Git Bash offers some relief from the file path limitation by handling symlinks differently. Installing Git for Windows with certain options can help resolve long path issues.

Steps:

Download the latest Git for Windows installer.
During the installation process, choose the option --no-symlinks under the “Select Components” section.
Proceed with the installation.

This configuration change helps Git handle longer file paths more effectively in certain scenarios.

7. Change File System (Advanced)

For advanced users who frequently encounter path length issues, switching the file system from NTFS (which has the 260-character limit) to ReFS (Resilient File System) can offer relief. ReFS supports longer file paths but is only available on Windows Server and certain editions of Windows.

Caution:

Switching file systems is a complex task and should only be done by experienced users or system administrators.

Frequently Asked Questions (FAQs)

1. What is the ‘Git filename too long’ error?

The “Git filename too long” error occurs when the combined length of a file’s name and its directory path exceeds the limit imposed by the operating system, usually 260 characters on Windows.

Enable long paths on Windows 10 and Git

If you run Windows 10 Home Edition you could change you Registry to enable Long Paths.

Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem in regedit and then set LongPathsEnabled to 1.

If you have Windows 10 Pro or Enterprise you could also use Local Group Policies.

Go to Computer Configuration > Administrative Templates > System > Filesystem in gpedit.msc, open Enable Win32 long paths and set it to Enabled.

git config --system core.longpaths true

Tested same on Windows 11 Pro 22H2 and it works. Thanks.

Hi,

I am trying to clone the repository from Bitbucket to the VS Code using Git cloning and I am getting failures (Red) on few folders particularly on Portal Folders. Thought it might be because of Long Paths so I have tried above suggestion but still it didn’t work and I am using Windows 11 Pro. Could you able to suggest any resolutions for this issue? Thanks

the git client you’re using must also turn long filenames on. try this:

git config --global core.longpaths true

Thank you so much for your quick response @naikrovek . I tried running that command yesterday but still no luck. I have tried running using Git CMD and also Git Bash. Can you able to provide some instruction steps how to turn long file names I will try just in case…Many thanks in advance.

@naikrovek , Thank you again…I am very new to all these so I am still learning. I will go through the link that you have provided and see if I can able to resolve my problem.

thank you so much mr. leo

When you encounter a «filename too long» error in Git, it typically means that the combined length of the file path exceeds the operating system’s limitations, which can be resolved by shortening the path or using Git’s configuration adjustments.

git config --global core.longpaths true

Understanding the Problem

What Does «Filename Too Long» Mean?

The «filename too long» error occurs when you attempt to perform Git operations on files whose total path length exceeds the maximum limit set by the filesystem or operating system. Each filesystem has specific constraints on the length of filenames and paths, which can lead to this frustrating error.

Why Do Long Filenames Cause Issues?

When using Git, long filenames can trigger errors due to limitations imposed by various filesystems, such as NTFS (commonly used in Windows) and ext4 (commonly used in Linux). For instance, NTFS has a maximum path length of 260 characters, while ext4 typically allows for longer paths but still has practical limits. In addition to this, different operating systems impose their own constraints that can complicate file management across platforms.
